PARIS, May 23 (Reuters) - European luxury shares tanked on Friday as U.S. President Donald Trump said he is recommending a straight 50% tariff on goods from the European Union starting on June 1.

Europe’s luxury industry, producing handbags, shoes, fashion items and champagne among other prized goods, is highly exposed to the U.S. market, which was seen as the sector’s best hope for growth this year as Chinese demand lags.
